Also can incrementally increase.Wherein used with HDPE bellowss relatively broad.High-density polyethylene double-wall winding pipe is with high-density polyethylene
Alkene (HDPE) is primary raw material, is entwined under hot melt state using special expressing technique, is built as a kind of new chemistry
Material, HDPE binary wall twisting and pipes have in light weight, corrosion-resistant, tube wall is smooth, conveyance capacity is big, good seal performance, service life are long,
The advantages that easy transportation and installation and fast speed of application, got a lot of applications in China's sewerage system process of construction.But
It is that existing double-wall winding corrugated pipe is in intensity or relatively weak, in some cases can not normal use.
Utility model content
The technical problems to be solved in the utility model is：There is provided a kind of intensity bigger HDPE bellows structures.
The solution that the utility model solves its technical problem is：Tri- layers of composite intensifying tubes of HDPE, it is single to include extrusion
Member, the extrusion unit are mutually closely wound together, and the extrusion unit includes the first cuboid and the second cuboid, and described the
One cuboid and the second cuboid are hollow setting；The lower end of first cuboid and the second cuboid is connected as a single entity, described
First cuboid and the second cuboid point are listed in the left and right ends of extrusion unit, between first cuboid and the second cuboid
Provided with air blanketing, the width of the air blanketing is 0.8-1.1 times of the thickness of the right side wall of the first cuboid；It is described adjacent
Pass through adhesive linkage bonding forming between two extrusion units；Also include enhancement layer, the enhancement layer is covered in extrusion unit
Outside, and the thickness of described enhancement layer is 0.5-1.2 times of the thickness of the madial wall of the first cuboid；Described extrusion list
Member, adhesive linkage and enhancement layer are HDPE material.
As the further improvement of above-mentioned technical proposal, first cuboid is to wait wall thickness component.
As the further improvement of above-mentioned technical proposal, the complete phase of shape of first cuboid and the second cuboid
Together.
The beneficial effects of the utility model are：The utility model extrudes the shape and structure of unit by improving so that extrusion
Unit includes three middle cavitys in the vertical so that the tubing intensity after winding is higher；Tubing also wraps from inside to outside simultaneously
Three layers of wall are included, wherein two layers of wall for extrusion unit, outermost layer is enhancement layer, and the pipe of three layers of wall construction also substantially increases pipe
The intensity of material.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described.Obviously, described accompanying drawing is part of the embodiment of the present utility model, rather than entirely
Portion's embodiment, those skilled in the art on the premise of not paying creative work, can also obtain it according to these accompanying drawings
His design and accompanying drawing.
Fig. 1 is tubing expansion section view of the present utility model.
Embodiment
Design, concrete structure and caused technique effect of the present utility model are carried out below with reference to embodiment and accompanying drawing
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is part of the embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area
The other embodiment that art personnel are obtained on the premise of not paying creative work, belong to the model of the utility model protection
Enclose.In addition, all connection/annexations being previously mentioned in text, not singly refer to component and directly connect, and refer to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to form more excellent draw bail.Each technology in the invention is special
Sign, can be with combination of interactions on the premise of not conflicting conflict.
Reference picture 1, tri- layers of composite intensifying tubes of HDPE include extrusion unit 1, and the extrusion unit 1 is mutually closely wound
Together, the extrusion unit 1 includes the first cuboid 11 and the second cuboid 12, the cuboid of the first cuboid 11 and second
12 be hollow setting；The lower end of first cuboid 11 and the second cuboid 12 is connected as a single entity, first cuboid 11 with
Second cuboid 12 divides the left and right ends for being listed in extrusion unit 1, is provided between the cuboid 12 of the first cuboid 11 and second
Air blanketing 13, the width of the air blanketing 13 are 0.8-1.1 times of the thickness of the right side wall of the first cuboid 11；The phase
Pass through the bonding forming of adhesive linkage 2 between adjacent two extrusions unit 1；Also include enhancement layer 3, the enhancement layer 3 is covered in extrusion
The outside of unit 1, and the thickness of described enhancement layer 3 is 0.5-1.2 times of the thickness of the madial wall of the first cuboid 11；It is described
Extrusion unit 1, adhesive linkage 2 and enhancement layer 3 be HDPE material.When production, extrusion is squeezed out from mould first
Unit, extrusion unit have just automatically formed the first cuboid and the second cuboid when shaping, and the first cuboid and the
The lower end of two cuboids closely connects together, so as to improve shaping after tubing intensity, although the double-walled of existing market
The extrusion unit that bellows has rectangle is entwined, but is simply bonded one simply by glue between extruding unit two-by-two
Rise, so that overall intensity is little.And three layers of composite intensifying tube of the present utility model is by extrusion unit formation
When, ensure that and also include an air blanketing between cuboid two-by-two, go the ring for improving tubing firm using air blanketing
Degree.Meanwhile cover one layer of HDPE enhancement layer again outside extrusion unit, so that tubing is after shaping, included outward by interior
There are three layers of wall, improve the intensity of tubing.One layer of HDPE film is covered outside extrusion unit although in the prior art, having,
But change HDPE films and simply play an erosion-resisting effect, because its thickness is relatively low, it is difficult to it is strong to play an enhancing
The effect of degree, and enhancement layer of the present utility model is quite different, and by increasing its thickness, pipe is improved while air blanketing is protected
The intensity of material.
Preferred embodiment is further used as, first cuboid 11 is to wait wall thickness component.First cuboid
11 is identical with the shape of the second cuboid 12.By rationally setting the shape and structure of extrusion unit, extrusion unit is improved
Convenience is produced, and improves the final product quality of extrusion unit.
Better embodiment of the present utility model is illustrated above, but the invention be not limited to it is described
Embodiment, those skilled in the art can also make a variety of equivalent changes on the premise of without prejudice to the utility model spirit
Type or replacement, these equivalent modifications or replacement are all contained in the application claim limited range.
